Quantify
geographic sampling bias with sampbias}
Human biases play a
large role in the data we collect about species. Here we show a simple
method to quantify the bias of roads, cities, rivers and airports on
species observations of legless lizards in the Northern
Territory
Multiple
colour scales in choropleth maps with ggnewscale}
Using
multiple colour scales can be a great way to visually differentiate
between geographic categories on a map. Here, we demonstrate this by
creating a choropleth map to represent the density of plant records from
the ALA across bioregions in Australia, and add multiple colour scales
to differentiate marine and terrestrial records

plant species data by hexagon to make a 3D hex map
Making
plots eye-catching can be useful for science communication. Here, we
show how to make 3D plots in R with the rayshader package
by visualising the number of species identified from ALA observations
